BEE 473 Watershed Engineering fall 2004 CULVERTS AND PIPE SPILLWAYS The hydraulics of pipes can be complicated, but for design purposes we only need to consider a couple basic relationships from fluid mechanics and use a few culvert design rules to avoid situations with unpredictable flow behaviors. In most cases there are three basic flow conditions that engineers consider, pipe flow with a submerged outlet, pipe flow with a free outlet, and orifice flow at the inlet (A, B, and C, below, respectively). Submerged outlet conditions are determined by the depth of flow below the pipe or culvert. To determine whether the culvert will experience pipe or orifice flow, compare the neutral slope, sn, to the actual slope of the pipe, s; if s > sn then orifice flow will persist. Conceptually, in a steeply sloped culvert, inertial forces will dominate over frictional forces and the flow will be controlled at the culvert opening (orifice flow).
